Destructive Photon Echo Formation in Six‐Wave Mixing Signals of a MoSe2 Monolayer

Autor: Thilo Hahn, Diana Vaclavkova, Miroslav Bartos, Karol Nogajewski, Marek Potemski, Kenji Watanabe, Takashi Taniguchi, Paweł Machnikowski, Tilmann Kuhn, Jacek Kasprzak, Daniel Wigger

Publikováno v: Advanced Science, Vol 9, Iss 1, Pp n/a-n/a (2022)

Abstract Monolayers of transition metal dichalcogenides display a strong excitonic optical response. Additionally encapsulating the monolayer with hexagonal boron nitride allows to reach the limit of a purely homogeneously broadened exciton system. O

Using four-wave mixing microscopy, we measure the coherent response and ultrafast dynamics of excitons and trions in MoSe$_2$ monolayers grown by molecular beam epitaxy on thin films of hexagonal boron nitride. We assess inhomogeneous and homogeneous

Controlled Coherent Coupling in a Quantum Dot Molecule Revealed by Ultrafast Four-Wave Mixing Spectroscopy

Semiconductor quantum dot molecules are considered as promising candidates for quantum technological applications due to their wide tunability of optical properties and coverage of different energy scales associated with charge and spin physics. Whil

Influence of local fields on the dynamics of four-wave mixing signals from 2D semiconductor systems

Autor: Thilo Hahn, Jacek Kasprzak, Paweł Machnikowski, Tilmann Kuhn, Daniel Wigger

Publikováno v: New Journal of Physics, Vol 23, Iss 2, p 023036 (2021)

In recent years the physics of two-dimensional semiconductors was revived by the discovery of the class of transition metal dichalcogenides. In these systems excitons dominate the optical response in the visible range and open many perspectives for n

Coherent Dynamics of a Single Mn-Doped Quantum Dot Revealed by Four-Wave Mixing Spectroscopy

Autor: Jacek Kasprzak, Daniel Wigger, Thilo Hahn, Tomasz Jakubczyk, Łukasz Zinkiewicz, Paweł Machnikowski, Tilmann Kuhn, Jean-François Motte, Wojciech Pacuski

Publikováno v: ACS Photonics. 9:1033-1041

For future quantum technologies the combination of a long quantum state lifetime and an efficient interface with external optical excitation are required. In solids, the former is for example achieved by individual spins, while the latter is found in

Publikováno v: 2D Materials. 10:025027

Quantifying and controlling the coherent dynamics and couplings of optically active excitations in solids is of paramount importance in fundamental research in condensed matter optics and for their prospective optoelectronic applications in quantum t

Tunnel-coupled pairs of optically active quantum dots - quantum dot molecules (QDMs) - offer the possibility to combine excellent optical properties such as strong light-matter coupling with two-spin singlet-triplet ($S-T_0$) qubits having extended c
